Material Properties Flashcards
1
Q
Stress
(definition)
A
The pressure a material is under (force/area)
2
Q
Strain
(definition)
A
A measure of how much a material has stretched
3
Q
Ductile
A
Can be drawn into wires as it has a large plastic region
4
Q
Brittle
A
Snaps easily as little plastic deformation
5
Q
Hardness
A
Hard to scratch with compressive force
6
Q
Toughness
A
Can absorb lots of energy without breaking
7
Q
Malleability
A
Can be bent into shapes
8
Q
Youngs’ Modulus
(Definition)
A
A measure of the stiffness of a material: how much it will extend (strain) under a given pressure (stress)
9
Q
Ultimate tensile strength
A
The maximum strength a material can withstand
10
Q
Breaking stress
A
A measure of the the stress needed to break something
11
Q
Strong
A
Requires a lot of force to break
